The typical Internet ‘athiest’ bully may declare that ‘athiesm’ is against all religions because religion is about ‘God’— usually meaning the God of the Bible. But we want to look into the question more deeply than that. And, as is so often the case, we need to start at the dictionary.
The word ‘religion’ in English comes from the Latin word ‘religio.’ The first definition in my dictionary says ‘belief in or worship of God or gods.’ But there is a second. ‘A specific system of belief or worship, etc, built around God, a code of ethics, a philosophy of life, etc.’ So atheism is a specific system of belief built around a philosophy of life. That is a religion. Though it is more popular in many circles to call a non-theistic religion a ‘philosophy of life.’
‘Athiests’ may complain at this. But they shouldn’t. Why do atheists have freedom of religion in the United States and elsewhere? Certainly not because atheism was considered to be a socially responsible viewpoint worthy of protection by the United States’ Founding Fathers. In fact I heard of an early murder case that went unprosecuted because the eyewitness was an atheist who at the time could not be sworn in as a witness in court. Atheism is protected now because it is considered a religion— in the ‘philosophy of life’ sense, not in the ‘code of ethics’ or ‘worship of God/gods’ senses.
As a system, atheism lacks a lot that other religions have. Religions usually have quite a few specific required beliefs, or dogmas. The only universal atheist dogma is ‘there is no god.’ To which some add other dogmas like ‘atheism is based on logic but we can’t say how,’ or ‘all atheists are logical and all God-believers are not’ or ‘God is evil and causes earthquakes’ or ‘if you don’t accept atheism you must be a Bible-believing Evangelical Christian’ or ‘atheism is so logic-based and science-based it is obviously true and needs no proof.’ But all atheists don’t believe all of those.
Atheism also lacks a moral code— though atheists themselves may have a moral code from some other source or philosophy. There is nothing within the belief of atheism to tell us to love our neighbor and help our neighbor, rather than hate our neighbor and steal from our neighbor. The Founding Fathers of the US thought that belief in a God, an afterlife, and afterlife punishments and rewards was a necessary thing to make one a good and law-abiding citizen. Atheists don’t believe that and I am sure that most of the more thoughtful/intellectual atheists do have some sort of moral code that does not contradict their atheism— though it is not require by atheism itself.
There are multiple kinds of atheists. There are rude atheists, like Madilyn Murray O’Hair and the internet ‘athiests,’ and there are simply people who don’t happen to belief in a God, for whatever reason. The beloved Christian apologist and writer C. S. Lewis was an atheist for a number of years. He doesn’t mention having mocked Christians or caused a fuss over his atheism, and I honestly can’t imagine the man he was ever bullying someone over their Christianity. If only he had written articles on atheism during his atheist years, he could have been a decent role model for atheists today. Though they would likely reject anything he’d written because he became a Christian and a defender of Christianity (a Christian apologist.)
What about an atheist who says ‘atheism isn’t a religion, it’s the truth!’ Well, first I would wonder if the atheist got that argument from the (Evangelical) Christians who say ‘(Evangelical) Christianity isn’t a religion, it’s the truth!’ Regardless of the source of the saying, I would say frankly: atheism is a religion. Evangelical Christianity, like Christianity in general, is a religion. There is nothing in the dictionary definition of ‘religion’ that says that a religion may not be true! And I would imagine that nearly all people regard their own religion as being true. If they don’t think it’s true, in what sense are they adherents of that religion? Christianity has a name for that state: a ‘nominal Christian’ is one who may say he is a Christian, for social or other reasons, but does not actually believe. So to say a ‘religion’ can’t be the truth is simply being illogical.
